摘要 为了研究祁东矿区地面变形及矿井突水等地质灾害现象,从分析上覆松散层岩性特征、大量钻孔资料和水文地质资料入手,结合两个基岩标钻孔部分土样的土工试验测试,研究了矿区内松散层的沉积来源及松散层岩性在垂向上及平面上的分布特征。通过对该区内上覆松散层的工程地质特性和水文地质特性与上覆松散层岩性在垂向上及平面上分布特征之间的相关关系进行了探讨,得出矿区内各含水层之间水力联系较小,四含水涌入是造成矿井突水的主要原因。 In order to investigate the geologic hazards such as ground surface deformation , water bursting in coal mines and etc. in Qidong mine area, beginning by analyzing the lithological features of overlying unconsolidated layers , large amount of borehole data and hydrogeological data, combining with the model test of soil mechanics of part soil samples from two lift marks of bedrock borehole, the origin of sediments and the distributing features of the lithological features of the overlying unconsolidated layers in vertical and lateral direction are studied. By discussing the relation between the characteristics of engineering geology and hydrogeology of the overlying unconsolidated layers and the distributing features of the lithological features in vertical and lateral direction in this zone , the conclusions are achieved that the hydraulic connections among each aquifer is comparatively lesser and that the inbursting of the fourth aquifer water is the main reason of the water bursting in coal mines.
